I noticed a peculiar black splotch all over the site images. Some were on the ground and others seemingly oozing out of a hole in the rocks. Below are five different instances of this splotch. Anybody got any ideas on the ooze? BTW I was very particular in my selections making sure I wasn't looking at shadows.

An image shown today on the NASA site. View of the Delta in Perseverance crater. I noted there are a lot of odd looking things to spend time on, but these three stood out as being the oddest and not a possible result of combined rocks that appear to be a single object. There is a lot of this going on in these images, where two or more rocks combine in a flat plane and look to be s single object. That is an area to be very careful about when trying to figure out what the heck these things might be.
A is a really neat engraving of a triangle on the tip of a rock. There is a central circle or EYE in it.
B is a squiggly line on the top of a large boulder. It looks like it could be a vein of material inside the rock that was eroded. Could be anything lying there or actually part of the boulder.
C is a flat boulder mostly buried. There are several objects 'piled' on top which could be debris. they are different than the boulder upon which they lie.
Between B and C are several other interesting objects that look like debris different from the rocks but they also could be several rocks appearing to be a single object, so I discounted them.
New image up today is a little frustrating because of the heavy shadows facing the camera. However there is a lot of debris laying about. I marked a few things that stood out to me. Mars Perseverance Sol 23: Left Navigation Camera
A is hard to describe but it reminds me of a toy tank with the treads pointing slightly upwards at the front. I make it some type of machine debris.
B is a wing shaped object. Nasa would claim the wind eroded it into this shape as noted in one of its first image of the day pics. There is a symbol at the heart of this which I don't think the wind can actually etch symbols.
C Could be a broken off piece of B but it is rounded and tapers to a point, thing is it is also dished out along its length.
D a round cylinder
E is a flat square rock. There are also dozens of these around the site. This one could also be partially buried to the left and its shape might change if uncovered but it gives a pretty good impression of a flat rectangular foundation block.
Here is a Moai found in the panorama of the Perseverance. The colorization was done by George Haas. Not really sure what this thing is other than it looks like it has been sculpted to some degree. Now was that a natural sculpting or the hand of a Martian?
More sand worms and a balanced rock. This is another sandworm on the left of this image. On the right is a large rock balanced atop another. There are just so many of these all over. The other recurring rock formation is the rock partially in mid air. That will show a large shadow underneath the rock.
Keith Laney put up a Gigapan. I went looking for some of the objects I already found to see if he added any clarity with his magic. Here is his version of my second post above of object A
I posted the image on page one of this thread in the first days of the current mission. It came from a Laney Gigapan. I thought it looked like the base of a fluted column. I offer this now to show how much of a fluted column it does look like.
Perseverance Mars Perseverance Sol 62: Right Mastcam-Z Camera This is a rather interesting rock. I put an enlarged inset to show the rock pointed out by the black arrow at the top. Note that it is rounded and sheared off at the top. It is so cleanly sheared that it is almost flat. However looking at the left end of the rock we see another straight edge and that the rock is scooped out inside. There are numerous rocks in this image that are all broken off on the left side. One is gnarled and looks like a broken open egg. Additionally there are many large rocks that are split in place. What could have been the mechanism to break these large rocks into pieces?
I am not trying to be a naysayer, I just see the object in this particular image a little differently. Item #1 was posted on the various boards recently and I pointed out that it was actually a single rock that had been split. Note the contours of the top and you should be able to see that they follow the same line on both pieces. I often get fooled by shadows trying to determine if I'm looking at one or two rocks making up the object. I am astounded by how many large stones there are in this site that have been similarly split and lie together on the ground. I noted a bunch of rocks with the small letter a. These are squared rocks that most likely are part of ruins. Those marked with a small b have a circular pattern like a spoked wheel on the top.
Staying with The same grouping of Images from Sol 62 through 65 here is a really odd item. This looks like a box that has one end broken off. The wall of the box persists while the insides are gone through half the box.
The letter b in this image indicates a curved rock similar to the one pointed out by ArtAlienTV in a video that he said was a statue arm and hand. In that video there was another rock just behind that one similarly curved. b in this image shows almost the same type of curve. In this case I think it could be part of a doorway arch. In the boxed off area to the right of this image are four objects grouped together as follows: a This is a bit too far for better definition but I see it as a rounded object that has a plate on the vertical in the center and two black spots. b is half a round wheel like rock. Reminds me of a grinding wheel. c Is a large square rock, this is pointed out because it is with the other objects, by itself it could be nothing. d is the doorway arch.
Working along with Perseverance on Mars. Today's posting shows two large boulders. We know this crater was filled with flowing water. We also know there is heavy indication of a former nuclear war according to radiation readings on the planet. That makes these two boulders more interesting IMHO! #1 is half a boulder sitting all by itself. The other half is no where to be seen close by. Just what mechanism caused this to happen? The creation of the crater itself? or was it the result of some other massive explosion? #2 is one of Many boulders all over this site. Sitting quietly but split completely in two. What force of nature brought that about?

Jim, the split may show evidence of water.
Any water in these rocks will freeze and expand at night when the atmosphere gets really cold and then during mid-day when the rock heats up it could form cracks. The rock may even explode during the night because of the expansion of the freezing making it difficult to find any of the broken pieces near by.
Here is an illustration showing the freezing and thawing of rocks.
Notice the second rock in this illustration looks a lot like your sand-worms...LOL
